My goal is simply to append to the DOD attribute table whether it falls within USGS, NCALM, or NOAA range, or multiple. Also, within the attribute table for USGS, NCALM, and NOAA, it indicates the name of the .las file by which LiDAR is downloaded, I would like to add that field as well. I do not have any corresponding ID fields by which to join.

So, for example, let's say I have a military base in North Carolina; the entire state of NC is covered by USGS data, so I simply want all DOD polygons within NC to have "USGS" in the new field, "Agency." Also, let's say the file name is "PJCT_NAME NC_Phase2_2003", I would like a field that indicates that as well.

If you are using ArcGIS, you might look into using a spatial join. You might also just do an intersect which should carry over any of the attributes from one layer to another...but it will probably get messy.
